Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a schematic diagram of the overall structure of a multifunctional cigarette lighter of the present disclosure;

(2) FIG. 2 is a circuit diagram of a multifunctional cigarette lighter of the present disclosure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(3) As shown in FIGS. 1-2, a multifunctional cigarette lighter, comprising a cigarette lighter body 1, a power plug 2 provided on the cigarette lighter body 1, a control unit and a display unit.

(4) Among other things, the power plug 2 is matched with the vehicle cigarette lighter socket for supplying power to the entire cigarette lighter.

(5) The control unit is configured to connect to the on-board warning light control, and includes a control circuit board for synchronously acquiring the working mode of the on-board warning light, for example, writing the control circuit in the form of a single-chip microcomputer; and, correspondingly, the control circuit board is connected to the on-board warning light through the signal control line 3.

(6) Specifically, the circuit diagram of a control circuit board of this embodiment is shown as FIG. 2. Preferably, the program on the control circuit board may be identical to the program in the on-board warning light.

(7) The display unit is configured to synchronously display the working mode of the on-board warning light, and includes a plurality of indicator lights 4 for synchronously displaying the working mode of the on-board warning light, wherein, the indicator lights 4 may select to use LED indicator lights which may display multiple colors. Preferably, the number of the indicator lights 4 may be 6-14, and for example, 10. The plurality of indicator lights 4 are electrically connected to the control circuit board.

(8) Specifically, the control circuit board in the control unit of this embodiment may have the identical working mode program to that in the on-board warning light. The control circuit board controls the plurality of indicator lights 4 in the display unit to synchronously display the working mode of the on-board warning light, such as blinking, flowing, tailing and constant lighting, and the like. The status displayed by the plurality of indicator lights 4 may be synchronized with the status displayed by the external on-board warning light. For example, when the on-board warning light is displayed as blinking state, the plurality of indicator lights on the cigarette lighter body may be synchronously displayed as blinking state.

(9) Referring back to FIG. 1, the plurality of indicator lights 4 in the display unit of the present embodiment may be disposed on the end surface 5 of the cigarette lighter body that is distal to the power plug. A switch control button 6 and a mode switching button 7 may be disposed on the end surface 5, wherein the switch control button 6 is configured to control whether the cigarette lighter and the on-board warning light are electrically powered. The mode switch button 7 is configured to adjust the working mode of the on-board warning light.

(10) Further, the plurality of indicator lights 4 in the display unit is preferably disposed to surround outside of the switch control button 6 and the mode switching button 7; correspondingly, the switch control button 6 and the mode switching button 7 may further be configured to be protruded from the end surface 5 of the cigarette lighter body that is distal to the power plug.

(11) The multifunctional cigarette lighter disclosed in this embodiment enables determination of the working mode of the on-board warning light directly through the working mode displayed on the display unit (the plurality of indicator lights) on the cigarette lighter body, which is visual and convenient.

(12) While the disclosure provides preferred embodiments as above, it is not intended to limit the scope of the disclosure. Any person skilled in the art, without departing from the scope of the disclosure, may make modifications. That is to say, equivalent improvements made in accordance with the present disclosure should be considered as encompassed by the scope of the present disclosure.
