Abstract
The utility model relates to a multiple-power input automatic voltage maintenance system for an air compressor, which comprises an alternating current power supply, a direct current power supply, a direct current motor, a wide voltage power supply converter, a double-pole double-throw selector switch, a pressure switch and a fuse. After the alternating current power supply is converted into the direct current power supply by the wide voltage power supply converter, and then the direct current power supply and the existing direct current power supply are connected to the double-pole double-throw selector switch for providing power for the direct current motor. Compared with the prior art, the air compressor can choose alternating current or direct current according to a using condition, in particular to driving people, the air compressor can be always arranged in an automobile trunk, when under a condition that the automobile is in urban with rare people or under a strong rainstorm sleet weather, the tyre burst is carried out, an automobile battery jar power supply is used for starting the air compressor so as to inflate the tyre, thereby providing convenience for people who are in trouble. The multiple-power input automatic voltage maintenance system has novel structure, flexible control, convenient usage, low cost, wide application range and promotional value.
Description
Technical field:
The utility model relates to a kind of air compressor control technique that is used for, and keeps system more specifically to a kind of many power supply input automatic pressures that are used for air compressor.
Background technique:
In the prior art, traditional air compressor adopts ac power supply mostly, and control technique is also ripe.But raising along with expanding economy and people's living standard, demand to air compressor in the family life increases year by year, in addition for the universal country of automobile, clan owning cars be unable to do without air compressor, particularly out on tours tyre break especially and is badly in need of just seeming even more important when repairing can't be found the repairing place again.Therefore develop family expenses air compressor problem a kind of miniaturization, AC/DC, that economize energy type and highlight, people expect the solution of this problem.
The model utility content:
The purpose of this utility model provides the many power supply input automatic pressures that are used for air compressor a kind of miniaturization, AC/DC, that economize energy type to keep system at the prior art deficiency.
The purpose of this utility model is to realize by following measure: a kind of many power supply input automatic pressures that are used for air compressor are kept system, it has ac power supply, DC electrical source, direct current generator, and its special way is to also have: wide voltage source transducer, DPDT diverter switch, pressure switch, safety fuse cutout; Described ac power supply inserts wide voltage source transducer through safety fuse cutout, wide voltage source converter output end connects DPDT diverter switch one side input end, DC electrical source directly connects DPDT diverter switch opposite side input end, is attempted by on the direct current generator wiring terminal with another output terminal of DPDT diverter switch after the DPDT diverter switch one output termination pressure switch.
Compared with prior art, the many power supply input automatic pressures that are used for air compressor that employing the utility model proposes are kept system, air compressor can select to use Ac or direct current according to service condition, particularly driving gang can be standing in automobile trunk with air compressor, when meagrely-populated in the countryside or strong quick-fried sleety weather is blown out in emergency circumstances, utilize automobile storage battery power initiation air compressor to be tyre inflation, from the predicament that is absorbed in, come out of and provide convenience.The utility model novel structure, control flexible, easy to use, with low cost, widely applicable, have promotional value.
Description of drawings:
Fig. 1 is the utility model example structure schematic representation.
Embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated:
In embodiment of the present utility model shown in Figure 1, a kind of many power supply input automatic pressures that are used for air compressor are kept system, it has ac power supply 1, DC electrical source 2, direct current generator 3, wide voltage source transducer 4, DPDT diverter switch 5, pressure switch 6, safety fuse cutout 7.Described ac power supply inserts wide voltage source transducer through safety fuse cutout, wide voltage source transducer converts 100V～240V ac power supply to the 12V DC electrical source, wide voltage source converter output end output DC crimping DPDT diverter switch one side input end, DC electrical source directly connects DPDT diverter switch opposite side input end, the DPDT diverter switch is a selector switch, can be that ac power supply or DC electrical source elect according to the service condition scene.Be attempted by on the direct current generator wiring terminal with another output terminal of DPDT diverter switch behind the DPDT diverter switch one output termination pressure relay.After the air compressor air storage tank inner air pressure reached certain value, pressure switch was cut off dc motor power automatically, and air compressor quits work, and after the air compressor air storage tank inner air pressure was lower than certain value, pressure switch was connected motor power automatically, started air compressor work.
The foregoing description does not constitute restriction of the present utility model, adopts the technological scheme that form obtained that is equal to replacement or equivalent transformation in every case, all drops within the protection domain of the present utility model.
