Abstract

The present invention provides a combustion device, which includes a fuel tank assembly and a candle wick. The fuel tank assembly includes a first tank, a second tank, a connection tube, and a switch. The capacity of the second tank is less than the capacity of the first tank. An end of the connection tube is connected to the first tank, and another end of the connection tube is connected to the second tank. The connection tube communicates with internal spaces of the first and second tanks. The switch is disposed between the first and second tanks so as to selectively open or close a channel interconnected between the first and second tanks. The candle wick is mounted in the second tank. Therefore, the combustion device is easy to use by the above structure.

First claim

What is claimed is:

1. A combustion device comprising:
a fuel tank assembly including a first tank, a second tank, a connection tube, and a switch, wherein a capacity of the second tank is less than a capacity of the first tank, wherein an end of the connection tube is connected to the first tank, and another end of the connection tube is connected to the second tank, wherein the connection tube communicates with internal spaces of the first and second tanks, wherein the switch is disposed between the first and second tanks to selectively open or close the connection tube interconnected between the first and second tanks;
a candle wick mounted in the second tank,
wherein the first tank has an opening,
wherein the fuel tank assembly further includes a blocking member and a filling seat, wherein the blocking member is mounted on the opening and has a first connecting hole extended therethrough, wherein the filling seat is pivotally connected to the blocking member to be pivotable in relation to the blocking member between a sealing position and a filling position, and wherein the filling seat has a second connecting hole adjacent to the blocking member and selectively aligned to the first connecting hole of the blocking member, wherein when the filling seat is in the sealing position, the second connecting hole is not aligned to the first connecting hole, wherein when the filling seat is in the filling position, the second connecting hole is aligned to the first connecting hole, and

a flow guiding assembly including a support, a plurality of guide vanes, a first shield member, and a second shield member, wherein the support has an insertion hole, wherein the plurality of guide vanes is secured in an inner periphery of the insertion hole, wherein the first shield member is fixed at a side of the support and has a first end and a second end opposite to the first end, wherein the second shield member is disposed at the side of the support adjacent to the first shield member and has a first end and a second end opposite to the first end, wherein the first end of the second shield member is pivotally connected to the first end of the first shield member, wherein the second shield member is pivotable in relation to the first shield member between a closed position and an open position, wherein when the second shield member is in the closed position, the second end of the second shield member is attached to the second end of the first shield member, wherein when the second shield member is in the open position, the second end of the second shield member is detached from the second end of the first shield member to form a gap, wherein the plurality of guide vanes is disposed between the first and second shield members, and wherein the candle wick is disposed between the plurality of guide vanes.

2. The combustion device as claimed in claim 1 , wherein the switch is disposed between two opposite ends of the connection tube.

3. The combustion device as claimed in claim 1 , wherein the candle wick has a bottom end and a top end opposite to the bottom end, wherein the bottom end is inserted into the second tank, wherein the top end is exposed out of the second tank, and wherein the top end is higher than bottom edges of the first and second shield members in a plumb direction.

4. The combustion device as claimed in claim 1 , wherein the flow guiding assembly further includes a connector mounted around the second tank, wherein a bottom edge of the plurality of guide vanes is fixed to the connector, and wherein the first and second shield members are disposed on a side of the support opposite to the connector.

5. The combustion device as claimed in claim 1 , further comprising:
a housing including a base plate, a roof plate, and a partition plate disposed between the base plate and the roof plate, wherein a side of the partition plate adjacent to the base plate forms an internal space, and another side of the partition plate adjacent to the roof plate forms a viewing space, wherein the partition plate further has a through-hole communicating with the internal and viewing spaces, wherein the fuel tank assembly is disposed in the internal space, wherein a side of the first shield member opposite to the support is fixed to the partition plate, and wherein the first and second shield members are aligned to the through-hole.

6. The combustion device as claimed in claim 5 , wherein the housing further includes a rear plate and a front plate, wherein an end of the rear plate is connected to a side of the base plate, and another end of the rear plate is connected to a side of the roof plate, wherein a face of the rear plate is connected to a rear edge of the partition plate, wherein the front plate is pivotally connected to a side of the base plate opposite to the rear plate, wherein a side of the front plate opposite to the base plate is pivotable to be close to or away from the partition plate, and wherein the filling seat further has a filling portion disposed opposite to the blocking member, wherein when the filling seat is in the sealing position, the filling portion is not faced to the front plate, wherein when the filling seat is in the filling position, the filling portion is faced to the front plate.

7. The combustion device as claimed in claim 6 , wherein the housing further includes two side plates connected to the base plate, the rear plate, and two side edges of the partition plate.

8. The combustion device as claimed in claim 7 , wherein the housing further includes three first transparent members and a second transparent member, wherein each of the three first transparent members is formed as a transparent plate and is mounted between the roof plate and the partition plate, and wherein the second transparent member is formed as a transparent tube and is mounted between the roof plate and the through-hole of the partition plate.
