Description

Electronic language sterilising cabinet

This utility model relates to a kind of decontaminating apparatus.

The CN2053439 patent application discloses the bright multi-functional cabinet of a kind of electronic sterilization name, is provided with ozonator in this electronic disinfector, and relative set the ozone generation power-supply controller that power supply is controlled to ozonator.Ozone generation power-supply controller is made of AC power interface, timer and booster.Though above-mentioned electronic disinfector has certain sterilizing function, but, misuse in the disinfection cabinet sterilization not thoroughly or the phenomenon of not passing through sterilizing objects thereby be easy to take place user because of it can not show its state of living in (finish as not beginning as yet to sterilize, sterilize, sterilizing etc. state) clear for user, intuitively.Therefore, above-mentioned existing disinfection cabinet exists certain defective.

The purpose of this utility model provides a kind of electronic disinfector that can intuitively reflect its working condition.

Electronic disinfector of the present utility model is provided with ozonator in cabinet, cabinet is provided with ozone generation power-supply controller.Ozone generation power-supply controller has AC power interface, timer and booster.The input of booster connects AC power interface through timer, two sparking electrodes of the output termination ozonator of booster.In this utility model, also in ozone generation power-supply controller, be provided with buck rectifier, sound circuit, power amplifier and speaker especially.Wherein, the input of buck rectifier and outfan connect the power end of AC power interface and sound circuit respectively, the input of the output termination power amplifier of sound circuit, the output termination speaker of power amplifier.Like this, can utilize buck rectifier for sound circuit, power amplifier and speaker provide low-voltage dc power supply, make sound circuit send voice signal, power amplification circuit amplifies this voice signal, and then drive the speaker sounding, inform disinfection cabinet state of living in to user.Herein, sound circuit can adopt the existing fixed speech IC, and as automobile-used speech IC or similar circuit, the voice signal that only needs to conform to the disinfection cabinet duty to its input in advance gets final product.

Compare with aforementioned existing disinfection cabinet, the sound circuit structure of electronic disinfector of the present utility model by being provided with in the ozone generation power-supply controller, whether the voice that speaker is broadcasted conform to the disinfection cabinet duty are finished to sterilize convenience are provided thereby understand disinfection cabinet intuitively for user.Therefore, the above-mentioned improvement of this disinfection cabinet helps to guarantee sterilisation quality.In addition, according to user's needs, disinfection cabinet of the present utility model also can be made into the disinfect box similar with it, disinfection box etc.

Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Fig. 1 is the structural representation of disinfection cabinet among the embodiment.

Fig. 2 is the circuit cabinet figure of ozone generation power-supply controller.

Fig. 3 is the electrical schematic diagram of ozone generation power-supply controller.

As shown in Figure 1, the disinfection cabinet among the embodiment has cabinet 1, transparent cabinet closing door 2, magnetic rubber sealing joint strip 3, high frequency vacuum voltolising ozonator 4 and ozone generation power-supply controller 5.Magnetic rubber sealing joint strip 3 is fixed on the doorframe of cabinet 1, and a side of cabinet closing door 2 also is articulated on the doorframe of cabinet 1.Ozonator 4 is arranged on the top in the cabinet 1, and ozone generation power-supply controller 5 is arranged at the outer top of cabinet.

Shown in Fig. 2～3, the ozone generation power-supply controller in the present embodiment is made of AC power interface 6, timer 7, controllable silicon excitation booster 8, buck rectifier 9, sound circuit 10, power amplifier 11 and speaker 12.Wherein, the input of booster 8 connects power interface 6 through timer 7, the output termination ozonator G1 of booster 8, two sparking electrodes of G2.The input and output side of buck rectifier 9 connects the power end of AC power interface 6 and sound circuit 10 respectively, the input of the output termination power amplifier 11 of sound circuit 10, the output termination speaker 12 of power amplifier 11.In the present embodiment, timer 7 is time switch K2, and controllable silicon excitation booster 8 is made of controllable silicon SCR, transformator B2, diode D4, capacitor C and resistance R 1, R2.Sound circuit 10 is mainly regulated resistance R 3～R5, gating switch AN, relay gate J, state display lamp ZO2～ZO4 and diode D1～D3 by speech IC IC1～IC3, velocity of sound and is constituted, and audion BG is power amplifier.In sound circuit, gating switch AN has the gating contact to i, j and m, n, relay gate J has the gating contact to a, b and c, d, wherein, the a pair of gating contact i of gating switch AN, another of j contact among the j and gating switch AN is to gating contact m, the a pair of gating contact a of m contact among the n and relay gate J, a contact among the b is with the negative output terminal g that connects buck rectifier, gating contact m, another of n contact among the n and relay gate J is to gating contact c, d contact among the d is connected, gating contact i, i contact among the j, gating contact a, b contact among the b and gating contact c, c contact among the d respectively with fixing speech IC IC1, the power supply negative terminal 3 of IC2 and IC3 joins, herein, power supply negative terminal is promptly as the control end of each integrated circuit.One end e of the drive coil of relay gate J connects a utmost point of AC power interface, and other end f is connected with another utmost point of AC power interface through time switch K2.The voice signal outfan 4 of IC1, IC2 and IC3 is with the input that meets power discharging transistor BG, the power positive end 5 of IC1, IC2 and IC3 is with the positive output end h that connects buck rectifier, and the velocity of sound control end 6,7 of IC1, IC2 and IC3 links to each other with R5 with adjustable resistance R3, R4 respectively.State display lamp ZO2～ZO4 is serially connected with respectively between the positive output end h of 3 feet of IC1～IC3 and buck rectifier.

When using the disinfection cabinet of present embodiment, can import the voice signal of " for your health; please use the sterilization of this machine " (statement A) in advance to IC1, to the voice signal of IC2 input " please noting; sterilize " (statement B), to the voice signal of IC3 input " sterilization finishes " (statement C).Like this, when the AC power interface energized and when making on and off switch K1 closed, IC1 work is the output voice signal also, and this signal makes speaker broadcast statement A after power tube BG amplifies.At this moment, gating contact i, j connect among the gating switch AN, and m, n disconnect, and show that the display lamp ZO2 that does not carry out disinfection is bright.When making time switch K2 closed, controllable silicon excitation booster imposes high voltage to the two poles of the earth of ozonator G1, G2, ozonator work, and disinfection cabinet begins sterilization.At this moment, relay J gets electric adhesive, and gating contact a, b connect, and c, d disconnect.When pressing gating switch AN, gating contact i, the j of AN disconnect, and m, n connect, and IC1 quits work, and IC2 then begins the voice signal of output statement B, show and just also light at disinfectant display lamp ZO3 thereupon.When time switch resets when closing, sterilization finishes, the relay J outage discharges, gating contact a, b disconnect, c, d connect, and IC2 quits work, the voice signal of the corresponding beginning output statement of IC3 C, show that the display lamp ZO4 that sterilization finishes lights, thereby inform that with sound, light dual mode the user sterilization finishes.
