Outer cylinder body 1 earth terminal; Inner barrel 2 is electrically connected with 2KV high voltage negative.
The work process of above-mentioned ion generating apparatus is as follows: after the vehicle-mounted 12V power supply of connection, opening switch, by autotransformer, vehicle-mounted 12V power boost is supplied to inner barrel 2 to 2KV high voltage negative, by outer cylinder body 1 and inner barrel 2 two ends high voltage, positive and negative electrode electric current tendency is adopted to intersect, produce and ionize trigger point in a large number, produce a large amount of ionic weights, the output quantity of anion is: 500,000,000 anion/cubic centimetres.Fan starting simultaneously, by the ion blowout ionized out, reaches the effect producing ion.
As shown in Figure 4, described base 11 is provided with shell fragment 19, on the pedestal 11, the bottom of shell fragment 19 is connected with the positive pole of the secondary coil of high-tension transformer T1, and the top of shell fragment 19 is against on the outer cylinder body 1 of ion generating device 12 in the bottom fixed installation of shell fragment 19.
The operation principle of above-mentioned air purifier is as follows:
The input plug of vehicle power transducer is inserted in vehicle-mounted cigarette lighter seat, the output plug of vehicle power transducer inserts in the jack bottom shell of air purifier, make the negative pole conducting of outlet and vehicle power transducer, the positive pole conducting of power pin and power supply changeover device, thus on-vehicle battery voltage+12V is input to system by safety switch (shell is then safety switch conducting after closing);
After being input to system, first will through the power protecting circuit module of system;
Two-way is divided to export afterwards:
+ 5V LDO is exported on one tunnel, and LDO produces+5V voltage to the button on MCU, LED display module (this module is also controlled by MCU, opens or turns off), KEY(face shield, PK1 and PK2 namely in Figure 18) power supply;
Another road export, first through MOS switching tube, after export to FAN, adjustable voltage output module (supply module of high-voltage generator);
After face shield is pressed (after namely KEY presses), to MCU switching signal, after MCU collects KEY signal, open MOS switching tube, make two tunnels above export conducting, power supply starts to FAN, adjustable voltage output module (supply module of high-voltage generator) is powered, simultaneously, LED display module is also opened by MCU, so far, face shield starts to show blue light, FAN starts to turn, and high-voltage generator starts output voltage to ionic tube, and ionic tube then starts ionized air;
The output voltage of adjustable voltage output module (supply module of high-voltage generator) is adjustable, by the output voltage (i.e. the output voltage of high-voltage generator) of regulator potentiometer R26 then this module of scalable, can provide the voltage of 2KV-8KV.
KEY is button PK1 and PK2 in Figure 18, and these two buttons are (that circular circuit board) on face shield circuit board, and namely PK1 and PK2 down pressed by spring by face shield; After button is pressed, then produce PUSH1 signal, to single-chip microcomputer (MCU), (Q2, Q3 are controlled by single-chip microcomputer the 7th pin the turn-on and turn-off of single-chip microcomputer collection PUSH1 signal control Q2, Q3 and Q4 tri-audions; Q4 is controlled by single-chip microcomputer the 9th pin), control the break-make of Q2 and Q3, then control LED on and off, because LED is and is connected in the output of Q2 and Q3 (notices that Q3, R2, R4 this part circuit is reserved, be actually and there is no welding component, just have passed Q2 come control LED); The turn-on and turn-off simultaneously controlling Q4 then control two tunnels and export.
Single-chip microcomputer to Q2 and Q3 low level signal (by the 7th foot), then Q2 and Q3 conducting (Q2 and Q3 2 and 3 pins connect), single-chip microcomputer is to high level signal, then Q2 and Q3 turns off; Single-chip microcomputer is to Q4 high level signal (by the 9th foot), then Q4 conducting (i.e. 1 and 3 pins of Q4), after Q4 conducting, then Q1 conducting (the 2 and 3 pin conductings of Q1), after Q1 conducting, then start to power to FAN, and power to U2, namely two tunnels export whole conducting.
PUSH2 is the signal of switch S 2, it is be placed on the cup of depurator that S2 originally designed, S2 has two states, two states exports two kinds of signals (high and low) respectively to single-chip microcomputer, single-chip microcomputer collection is control U3(digital regulation resistance afterwards) output resistance, increase or reduce U2 resistance, then can regulate U2(adjustable voltage output module) output voltage, output voltage is large, then depurator is domestic (large spaces), output voltage is little is then automobile-used (little space), so S2 switch is depurator domestic or automobile-used gauge tap; This design is reserved, and present depurator does not use, and on circuit board, the components and parts of the circuit of this block also do not weld.
