Embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.As shown in Figure 1, Figure 2 and Figure 3, the utility model embodiment provides gas-cooker adapter, comprise: power selection circuit, power selection circuit comprises: dry battery power input interface 101, external power supply input interface 102, power change-over switch 103 and output interface 104; Dry battery power input interface 101, power change-over switch 103 and output interface 104 order series connection; External power supply input interface 102, power change-over switch 103 and output interface 104 order series connection; Power change-over switch 103 is for selecting external power supply input interface 102 or dry battery power input interface 101 to be communicated with output interface 104.
Concrete, power change-over switch 103 can be the switch that single-pole single-throw switch (SPST), double-point double-throw switch etc. have selection function.The effect of power change-over switch 103 is to select dry battery power input interface 101 to be communicated with output interface 104, or selects external power supply input interface 102 to be communicated with output interface 104.By selecting external power supply input interface 102 or dry cell input interface to be communicated with output interface 104, user can be waited when needed, choice for use civil power is to gas-cooker control module power (when civil power can normally provide in the situation of electric energy), or use dry battery power to gas-cooker control module power (when civil power cannot provide electric energy normally, just can use dry battery power to power to gas-cooker control module).Wherein, external power supply can be the long-acting power supplys (stabilized power supply that can power for a long time) such as civil power, large-capacity battery power supply, the civil power that occurred hereinafter, mains supply is all interpreted as extraneous power supply, or the long-acting power supply such as large-capacity battery power supply.
In order to improve the effect of use, power change-over switch 103 can be set to single-pole double throw relay, namely power change-over switch 103 is single-pole double throw relay, power change-over switch 103 comprises the first coil, the first normally opened contact and the first normally-closed contact, and the first coil is electrically connected to external power supply input interface 102; The first normally opened contact is electrically connected to external power supply input interface 102; The first normally-closed contact is electrically connected to dry battery power input interface 101.
