Technical scheme: a kind of disinfecting cabinet for toys circuit structure, comprise voltage conversion circuit, this voltage conversion circuit is rectification, filtering and mu balanced circuit, described voltage conversion circuit input is connected with power supply, voltage conversion circuit outfan by wire, be connected with ozonator, radiator fan and automatic child lock respectively and ozonator, radiator fan and automatic child lock and voltage conversion circuit outfan between the normally opened relay of connecting respectively, the coil in three relays forms circuit by wire and display control board and time switch respectively.
This utility model is compared with background technology, and the one, the 24V human safety voltage for disinfecting cabinet for toys operation provides, has avoided the generation of electric shock accidents; The 2nd, can automatic shutter disinfecting cabinet for toys cabinet door, prevented that disinfecting cabinet for toys is opened at work and scald accident occurs.
Accompanying drawing explanation
Fig. 1 is disinfecting cabinet for toys electrical block diagram.
Fig. 2 is the structural representation of display control board in Fig. 1.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1, Fig. 2.A kind of disinfecting cabinet for toys circuit structure, comprise voltage conversion circuit 1, this voltage conversion circuit 1 is rectification, filtering and mu balanced circuit, described voltage conversion circuit 1 input is connected with power supply, voltage conversion circuit 1 outfan by wire respectively with ozonator, radiator fan is connected and ozonator with automatic child lock, the normally opened relay 2 of connecting respectively between radiator fan and automatic child lock and voltage conversion circuit 1 outfan, both 220V alternating current power supply was through the rectification of voltage conversion circuit 1, after filtering and voltage stabilizing, export 24V unidirectional current, ozonator, radiator fan and automatic child lock are connected in parallel in voltage conversion circuit 1 outfan, ozonator, normally opened relay 2 and ozonator that radiator fan and automatic child lock are connected in series separately, radiator fan and automatic child lock are realized idle and operation by the open and-shut mode switching of relay 2, whether described relay 2 realizes the switching of its normal open switch by the coil electricity in relay 2, coil in three relays 2 is respectively by wire and display control board 3 and time switch 4 formation circuit, both the coils from parallel connection of coils in three relays 2 accessed a light current circuit, the time switch 4 of two relay 2 coil tandems that are also in series with the shift knob 33 in display control board 3 in this circuit and surely connect with ozonator and radiator fan.Described voltage conversion circuit 1 input voltage is 220 volts of alternating currents, and output voltage is 24 volts of unidirectional currents.Described relay 2 is the time relay.In described three relays, with two relay closes time consistencies of ozonator and Cascaded radiator fan, and be later than the relay closes time of connecting with automatic child lock with the two relay closes times of ozonator and Cascaded radiator fan.Described display control board 3 by display screen 31, setting key 32 and shift knob 33, formed and display control board 3 in setting key 32 be connected by wire with time switch 4.Described time switch 4 is electronic type time switch, both Preset Time then time switch by automatic disconnection.Described automatic child lock is electromagnetic lock.
