Description
[technical field]
The utility model relates to a kind of power supply change-over device that is used for gas heater.
[background technology]
Existing gas heater, because dry cell quality does not on the market pass a test, dry cell inferior raids market, cause the gas heater user to be not easy to choose good dry cell, even the user who has bought not the battery in Kaifeng and returned, be contained in to use on the chimney flue type gas heater and non-ignitable phenomenon can occur less than a week just having, use the Meter Test battery, do not had electricity, tested the battery of newly buying again, found undertension yet.Therefore the user still is hard to guard against when choosing battery, and worse is exactly, and the user takes for gas heater that problem is arranged, and causes obstruction for the popularization of gas heater.And, the use battery supply igniting that existing gas heater, great majority can only be single, in case dead battery or undertension just can't provide power supply to light a fire to gas heater, gas heater is just in paralyzed state, can't use.
[summary of the invention]
The purpose of this utility model is only can only rely on battery powered shortcoming at gas heater, and a kind of novel power supply change-over device is provided, and takes comparatively practical scheme, can connect easily and exchanges power supply type, is convenient to the demand of daily life.
The purpose of this utility model is achieved in that
A kind of power supply change-over device that is used for gas heater, it is characterized in that it is made up of AC/DC power supply adaptor and the power switcher that is arranged on the gas heater, on gas heater, also be provided with the electric loop of the dry cell power supply in parallel with power switcher, described power switcher comprises Direct current power source socket, and in Direct current power source socket, being provided with movable contact spring, an end of described movable contact spring is connected with the control point firearm.
Aforesaid a kind of power supply change-over device that is used for gas heater is characterized in that the end of described movable contact spring contacts with an end of the electric loop of dry cell power supply.
Aforesaid a kind of power supply change-over device that is used for gas heater, it is characterized in that described AC/DC power supply adaptor comprises power supply front-end processing network, rectifying and wave-filtering network, voltage stabilizing network, is provided with the B isolated area between power supply front-end processing network and the rectifying and wave-filtering network.
The utility model makes gas heater have civil power and dry cell two purposes, can make gas heater preferentially use civil power.Simple in structure, cost is low, and is applied widely, with original electric loop compatibility of gas heater, for condition has been created in the lasting use of gas heater.
[description of drawings]
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the electrical schematic diagram of the utility model power switcher.
Fig. 2 is the outline drawing of the utility model power switcher.
Fig. 3 is the electrical schematic diagram of the utility model AC/DC power supply adaptor.
[embodiment]
A kind of power supply change-over device that is used for gas heater, form by AC/DC power supply adaptor 1 and the power switcher 2 that is arranged on the gas heater, also be provided with the electric loop 3 of the dry cell power supply in parallel with power switcher 2 on gas heater, the internal wiring 23 of described power switcher 2 is connected with the control point firearm 4 of water heater.
AC/DC power supply adaptor 1, comprise power supply front-end processing network 11, rectifying and wave-filtering network 12, voltage stabilizing network 13, be provided with B isolated area 14 between power supply front-end processing network 11 and the rectifying and wave-filtering network 12, power supply front-end processing network 11 can be directly be connected with indoor 220V or 110V AC power, rectifying and wave-filtering network 12, voltage stabilizing network 13 are connected with cable 16, and the end of cable 16 is connected with DC plug 17.Power supply front-end processing network 11 can directly be plugged on indoor 220V or the 110V AC Power supply socket.Alternating voltage Up converts the 3V direct-flow steady voltage to through rectifying and wave-filtering network 12, voltage stabilizing network 13 after delivering to the B isolation by power supply front-end processing network 11, and the 3V direct-flow steady voltage is drawn by cable 16, DC plug 17 again.
Power switcher 2 is arranged on the outer cover of water heater 21, comprises the Direct current power source socket 22 that is arranged on the shell 21, and the inner of Direct current power source socket 22 is connected to internal wiring 23, and is provided with movable contact spring 24 in Direct current power source socket 22.The end of movable contact spring 24 contacts with an end of the electric loop of dry cell power supply 3.On Direct current power source socket 22, be provided with the latch 222 that matches with DC plug 17, when the DC plug 17 of AC/DC power supply adaptor 1 is docked with the dc power plug 22 of power switcher 2, on the latch that is inserted into Direct current power source socket 22 222 of DC plug 17, meanwhile, the neighboring of DC plug 17 contacts with movable contact spring 24, and stir movable contact spring 24 and outwards move, the electric loop 3 and movable contact spring 24 joints of dry cell power supply are disconnected because of movable contact spring 24 outwards moves originally.
On DC plug 17 insertion power switchers 2, the movable contact spring 24 of power switcher 2 cuts off the electric loop 3 of the dry cell power supply of gas heater, and power switcher 2 docks with the DC plug 17 of AC/DC power supply adaptor 1 simultaneously.After the butt joint, supply the voltage of coming just enters gas heater from power switcher 2 control point firearm 4, gas heater is worked on by AC/DC power supply adaptor 2.Power switcher 2 is connected with the control point firearm 4 of water heater after being responsible for exchanging electric loop 3 parallel connections of the power supply of coming from AC/DC power supply adaptor 1 or the power supply wiring 33 that uses dry cell and dry cell power supply again.
