A three-in-one handheld lighting device includes a casing unit, a torch unit, a whistle unit, and a thermometer unit. The torch unit includes actuating and press pieces, a lamp member having first and second leg terminals, and a battery unit having positive and negative terminals. The torch unit is in an off state when the actuating piece is disposed at a first position. The torch unit is in an on state when the actuating piece is moved to a second position, wherein the press piece pushes the first leg terminal to contact electrically the negative terminal such that the positive terminal is in electrical contact with the second leg terminal. |

DETAILED DESCRIPTION Therefore, the object of the present invention is to provide a three-in-one handheld lighting device that is capable of overcoming the aforementioned drawbacks of the prior art.
According to this invention, a three-in-one handheld lighting device comprises a casing unit, a torch unit, a whistle unit, and a thermometer unit.
The casing unit includes upper and lower casing members.
The upper casing member has a top wall, an upper surrounding wall that extends downwardly from a periphery of the top wall and that cooperates with the top wall to define an upper receiving space, and a partition wall that divides the upper receiving space into a torch receiving chamber and an air chamber opposite to the torch receiving chamber in a longitudinal direction.
The top wall is formed with an elongate switch receiving hole that is proximate to the partition wall and that extends in the longitudinal direction.
The upper surrounding wall is formed with a lamp hole distal from the partition wall.
The lower casing member is attached to a lower end of the upper surrounding wall of the upper casing member, and has a bottom wall and a lower surrounding wall that extends upwardly from a periphery of the bottom wall.
The bottom wall has an outer wall surface formed with a thermometer receiving cavity.
The torch unit is disposed in the torch receiving chamber, and includes an operating member, a light emitting diode lamp member, an insulating member, a battery unit, and a cover body.
The operating member is provided for controlling lighting of the torch unit, and includes a press piece and an actuating piece that extends upwardly and integrally from the press piece and that protrudes from the casing unit through the switch receiving hole.
The press piece has a bottom surface formed with a limiting groove extending in a direction parallel to the switch receiving hole, and a retaining groove formed above and in communication with the limiting groove.
The light emitting diode lamp member is disposed in the lamp hole, and has a head portion and a pair of spaced-apart first and second leg terminals connected to the head portion
