Fig. 1 is a first schematic circuit diagram according to an embodiment of the present invention.
Fig. 2 is a second schematic circuit diagram according to an embodiment of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1 and 2, the dual-system gas warmer comprises a gas pipeline and a control mechanism for controlling the on-off state of the gas pipeline, wherein the control mechanism comprises a relay 1, a remote control electronic valve 2 and a manual temperature control valve 3, a pin A of the relay 1 is connected with the anode of an external power supply, a pin B of the relay 1 is connected with the cathode of the external power supply, the relay 1 and the external power supply are connected in series with a control switch 4, a pin C connected with a movable contact part 11 of the relay 1 is respectively and electrically connected with the remote control electronic valve 2 and the manual temperature control valve 3, the remote control electronic valve 2 is electrically connected with a pin D which is normally open in the relay 1, the manual temperature control valve 3 is electrically connected with a pin E which is normally closed in the relay 1, the relay 1 is matched with the control switch 4, the mutual alternate use of the two valves can be realized, and the product can take the advantages of both, the adaptability of the product is improved.
Further, the dual-system gas warmer further comprises a temperature detection device 5, and the temperature detection device 5 is electrically connected with the remote control electronic valve 2 and the manual temperature control valve 3 respectively.
Further, a timing module 21 is arranged in the remote-control electronic valve 2.
