Description of the Invention: [Technical Field] The present invention relates to an electrostatic atomization device. [Prior Art] Patent Nos. 2006-3345-3 and 2007-21370 Both of the prior cases of the electrostatic atomization device have been disclosed, resulting in charged fine water droplets having a nanometer size. The electrostaticizing device supplies a helium voltage to the discharge electrode in a state where water is supplied to the distal end of the discharge electrode by capillary action. When high voltage is supplied to the discharge electrode, the water supplied to the discharge electrode will be charged. This will cause the repetition of the Rayldgh break to occur and cause electrostatic atomization of the water. As a result, the electrostatically atomizing device will produce charged fine water droplets having a nanometer size. In this type of static bribe recording, the self-osdllating flyback is used to switch the supply of the Ringing Ch〇ke Converter (RCC). Self-sewing back to the green turbulence is difficult to achieve around the high voltage to produce a variable pressure close to the _ _ (feedbaek eGil) so that the 胄 power MOS half-effect transistor (p〇werM 〇 SFET) for self-reinforcement. According to this, the self-vibration retrace = bell = circle conversion H does not need to set a separate subtraction, so that the circuit gauge can be small. Therefore, the self-oscillating retrace ringing choke converter is often used in the device, and for the self-vibration, the ringing converter is controlled; and the 'feedback control is often used according to The output cymbal easily activates the high rate MOS half-effect transistor turn-off switch (tum〇ff switch). In the case of electrostatic atomization, when the voltage under no load is too high, it will produce 201116336 atomization. Then: = rate =: When the relay device may not be able to perform static current to the drain of the electrode, the current will discharge the electrode, thus generating a large amount of ozone, resulting in a high ozone concentration. Piezoelectric problems, when too much current flows, it is desirable to suppress the generation of large amounts of ozone. BACKGROUND OF THE INVENTION The scale is to provide an electrostatic atomization device that avoids the generation of air power and large amounts of ozone at a low cost, and does not require the implementation of control. In an embodiment, the transformer of the electrostatically atomizing device comprises a primary coil and a secondary coil. The switching element is connected in series to the main coil of the transformer. Switching component drive circuit = for pulse signal to switch component, material change component for city operation, and from the secondary line of change b. The discharge unit includes a money-discharging pole. When the same electricity source is supplied to the discharge electrode, the discharge unit electrostatically atomizes the liquid supplied to the discharge to generate a plurality of charged fine droplets. The switching element driving circuit generates the ruggedness of the vibrating wheel, and the money compressor has the characteristic of drooping. The air discharge occurs at the discharge electrode, and when the liquid performs electrostatic fog (4), even if the load on the discharge material changes, the listening Ozone preset concentration or higher. The advantages and spirit of the present invention will be further understood from the following detailed description of the invention and the accompanying drawings.

It is said that the charge concentration is increased so that the high concentration repulsion breaks up the water and disperses (4) (4). The above-mentioned breaking 2 (called Rayleigh fracture) will occur repeatedly, and the electro-atomization will be carried out. = A large amount of charged fine water with nanometer size containing active material (10) ve spedes is shown in Figure 1 'DC power supply. The supply £ includes a positive terminal and a negative terminal for generating a η volt DC light.

The oscillating circuit 8 generates a pulse signal ps to activate and disable the high-power money half-field effect transistor 6, and the over-resistor 9 provides __PS to the high-power money half-field effect transistor 6 between the 201116336 terminal (gate terminal), the transistor 6 miscellaneous termination (four) pulse signal volt oxygen half-field effect 曰 6 dip transistor 6 will be activated or deactivated. The high-power gold device E is connected to the ^μ to start or deactivate the job. The main coil 5a of the transformer 5 is generated by the DC power supply. Result, high

The output voltage VG (in this embodiment, when the amount of water on the discharge electrode 3 is reduced in the mist 1 匕 device 1), the Taylor cone is small, and the distance from the distal end of the Taylor cone to the ground electrode 4 becomes long. , = the discharge current (output current 1 〇). In the electrostatic atomization device 1, when the amount of water on the pole 3 continues to decrease, the discharge does not occur on the discharge electrode 3 and the ground electrode 4. This causes the discharge scent discharge to occur between the discharge electrode "ground electrode 4. Therefore, electrostatic atomization will not proceed. On the other hand, the amount of water on the discharge electrode 3 of the 4* electrostatic atomization device 1 is increased. At the time, the :the taper will only be large and the distance from the distal end of the Taylor cone to the ground electrode 4 will be shortened, thus, a discharge current is applied. In the electrostatic atomization device 1, when the discharge electrode 3 is in the water When continuously decreasing, the distance between the ground electrode 4 and the water becomes extremely large, so that the & current will flow between the ground electrode 4 and the water. Therefore, the mist having the desired droplet diameter cannot be obtained ( Mist) In addition, a large amount of ozone will be produced, resulting in an increase in ozone concentration. This 'air discharge must be avoided, and when too much water accumulates on the discharge electrode 3 and the current flows through it, f also avoids the generation of a large amount of ozone. In other words, the 'transmission voltage Vo must be lower than the voltage value at which the air discharge occurs. (ie, air 201116336 discharge). In addition, when the wheel current lG is excessive, the output voltage v must be low 'so that the ozone concentration does not become high. To meet these demands' regardless of the amount of water on the discharge electrode 3, this implementation The electrostatic atomization device of the example sets the output voltage Vo outputted from the secondary coil 5b of the transformer 5: the amount of ozone generated by the air discharge to avoid the air discharge is less than or equal to the adjusted amount. The input voltage}Vo#, the money vibration rate And the pulse signal pulse width (starting time) is set, wherein the pulse signal ps is the gate terminal of the high-power MOS field-effect transistor 6 of the tremor circuit. ~° m in detail, the high-voltage (four) voltage device 5 contains large _Frequent capacitance. According to this, although the frequency of the vibration is increased, the efficiency of the high voltage generating transformer 5 will be lowered. Because of the high voltage generated as shown in Fig. 2, the variator 5 is weakened (dr〇〇(四) special=, - When the load current (output current) [〇) increases, the output power will decrease; when the field current Ιο is high, the output voltage v〇 will not increase. In this example, the gradient of the weakening characteristic It is changed according to the rate of vibration, and it will produce a much larger amount of ozone output than the subsequent amount. In other words, the LUF line shown in Figure 2 will be based on the recording and shock circuit 8 The pulse width (starting time) of the output pulse signal Ps changes. = In detail, in order to avoid air discharge, in the high-power transformer 5 reduction 2, for example, the output voltage v〇 must be set at least Less than or equal pressure. The discharge voltage Vd ' is not shown in Figure 3. Therefore, considering the high voltage generation change / ^ change and independent difference, the margin voltage (four) coffee her (four) ^ is set in the back voltage production pressure ^ 5 weakening Characteristic towel, output voltage V. It is set to reduce the electric difficulty obtained by subtracting the margin _vm from the air discharge surface. = (4) Attenuation (4) is obtained by the pulse width (starting time) of the pulse signal PS of the set surface (4) and the oscillating power. The figure ',' indicates that the ozone after the whole week is set to produce a curved green L2. The adjusted ozone mass production 201116336 The raw curve L2 indicates the output voltage v〇 and the output current Ιο corresponding to the preset tolerable ozone generation amount. That is, power. More precisely, as shown in FIG. 4, since the adjusted ozone L generation curve L2 forms a boundary, the amount of ozone generated in the range a is greater than or equal to the adjusted amount of ozone, and the range of ozone is generated. The amount is smaller than the adjusted amount of ozone. Therefore, the weakening characteristic (attenuation characteristic line L1) of the high voltage generating transformer 5 must be included in the range b. Accordingly, the weakening characteristic of the transformer 5 is generated at a high voltage (attenuation characteristic line Li) In order to avoid air discharge and to prevent the amount of ozone generated from being greater than or equal to the adjusted amount, for example, as shown in FIG. 5, the output voltage v〇 must be at least greater than or equal to the air discharge voltage Vd (including the margin voltage Vm), And the power needs to be less than or equal to the adjusted amount of ozone to generate the power set by the S3. The weakening characteristic (the weakened characteristic line L1) shown in FIG. 5 is transmitted through the pulse signal PS which is output from the oscillation frequency. The frequency of the high voltage generating transformer 5 shown in Fig. 5 is transmitted through tests, experiments and calculations. In addition, in this embodiment, the frequency of the oscillation and the oscillating circuit are obtained. The pulse width (starting time:) of the output pulse signal PS of 8 is set, so that the electrostatic atomizing device 1 operates according to the weakening characteristic shown in FIG. 5, and the seismic circuit 8 provides the pulse signal ps to the high power metal oxygen. Half-field effect • The body 6' pulse signal PS has the vibration plane rate and pulse width ^ time as shown in Fig. 5, to deactivate the high-power gold-oxygen half-field effect crystal in this case. τ 'Wire-f electrode 3 The amount of water on the electrospraying device 1 can still avoid the air discharge and the generation of a large amount of ozone. Furthermore, the present invention does not need to detect the output voltage Vo or the output current 1〇, and does not need to be based on the detected output. The electric or output current (four) feeds the high-power golden half-field effect transistor 6. According to the invention, the invention is not capable of feeding back the control circuit that controls the output of the f f1 and the expensive circuit. Therefore, the electrostatic atomization Device 1 can be used for Eve components and lower The cost is manufactured. Next, referring to Fig. 6, the high voltage generating circuit 2 for the electrostatic atomizing device 1 will be described. As shown in Fig. 6, the shock circuit 8 includes a comparator u. The comparator (10) includes a positive input W. Non-inverting input terminal. The series circuit provides partial voltage to the positive input terminal. The series circuit includes a variable resistor 拠 and a first resistor (four), and the variable resistor 拙 and the first-resistance Wei _ are in DC county The positive input terminal and the negative input terminal are connected in series between the positive input terminal and the negative input terminal of the DC power supply HE and the variable resistor Rb and the first resistor are connected in series with each other. The voltage (squeezing pressure) at the connection point (node N1) of the variable resistor Rb and the first resistor R1 is raised to the positive input terminal of the comparator U as the input voltage VI. Further, the positive input terminal of the comparator 11 is connected to the output terminal of the comparator 11 through the second resistor scale 2. A negative input (inverting input) is connected to the negative terminal of the DC power supply E through the capacitor C1. Furthermore, the negative input of comparator n is connected to the output of the scent via a third resistor. Using the oscillating circuit 8 of the comparator 11 to generate a pulse signal ps at its output, the pulse, the signal PS has a square wave 'and includes an oscillation determined by the resistance value of the third resistance 3 and the electric valley of the capacitor C1. frequency. The pulse width (starting time) or frequency of the positive pulse width (S at startup) is adjusted by adjusting the resistance value of the variable resistor Rb. / In this embodiment, the frequency and pulse width (starting time) of the pulse signal PS are preset. As described above, the weakening characteristic of the high voltage generating transformer 5 shown in Fig. 5 is obtained by a prior side test, experiment, and calculation. Furthermore, the oscillation frequency and the pulse width (starting time) of the pulse signal ps outputted from the oscillation circuit 8 (comparator 11) are set to 'the electrostatic atomization device 1 according to the attenuation characteristic 10 201116336 shown in FIG. 5 Operation. In other words, 'pulse signal? The oscillation frequency and pulse width (starting time) of 8 are set so that the generated output voltage ν 〇 is less than or equal to the voltage value (air discharge voltage) at which the air discharge occurs, and can be reduced when excessive output current 1 〇 flows. The voltage Vo is output to prevent the ozone concentration from becoming high. In this embodiment, the resistance value of the variable resistor Rb is adjusted to simply set the oscillation frequency and pulse width (starting time) of the pulse signal PS.

The emitter terminals of the NPN transistor ι^ΡΝΡ transistor T2 are connected to each other. The junction point (node N2) of the NPN transistor τ 1 and the PNP transistor T2 is connected to the gate terminal of the high-power MOS field-effect transistor 6 through the resistor H93⁄4. When the pulse signal ps output from the output of the comparator 11 has a high level, the NPN transistor T1 will be activated and the PNpf crystal T2 will be deactivated. The junction has an I2 volt system high turn-on that is supplied to the gate terminal of the high god MOS field effect transistor 6, to activate the high power MOS half field effect transistor 6, and the DC power supply Ε will supply power to the high voltage generating transformer 5 The main coil 5 & On the other hand, when the pulse signal 卩§ output from the output of the comparator n has a low level (10) and the pulse signal PS is lost, the transistor m is stopped and the PNP transistor T2 is activated. As a result, a low level voltage having a volt volt is supplied to the high power MOS field-effect transistor 6_extreme to activate the high-power MOS field-effect transistor 6, and no power is supplied to the high-voltage generating transformer coil 5a. η 201116336 Half-field effect transistor 6 is based on the comparison of the pulse pressure of 1111: or deactivated. This will intermittently supply power to the high voltage generating transformer 5. The second voltage of the coil height will be generated at the high voltage source. The half-wave rectification 1 will increase the secondary coil %4. Laijin spurt, the output voltage ν ki between the 1 electrode 3 and the ground electrode 4, ki, 5 kV. The jitter frequency and the pulse width (starting time) of the pulse signal ps generated by the comparator 11 are set to obtain the output voltage V of the high voltage generating variable weakening characteristic 4. It is at least less than the scale of the air discharge pressure 'f power system is less than or equal to the adjusted ozone amount production curve L2. This avoids the generation of the line discharge and prevents the amount of reduction from becoming larger than the adjusted amount. Therefore, when too much current lG flows, it is not necessary to perform complex __ control and reduce the output voltage Vo. The output voltage % generated by the electrostatic atomization device 小于 will be less than or equal to the light when the discharge occurs (air discharge voltage) . As a result, the amount of water which does not flow on the discharge electrode 3 changes depending on the situation, and the electrostatic atomization device 1 will prevent the occurrence of air discharge and generation of a large amount of ozone. Further, in this embodiment, the oscillation circuit 8 is formed by the comparator n. Therefore, compared with the LC shock circuit or the like, the oscillation frequency of the pulse signal generated by the simple circuit structure is relatively constant. Moreover, in this embodiment, the oscillation frequency of the pulse signal PS2 can be easily changed by changing the miscellaneous surface of the URb. This makes it easy to obtain the desired low voltage generating transformer 5 with reduced characteristics. It will be apparent to those skilled in the art that the present invention may be practiced in many other specific forms without departing from the scope of the invention. In particular, it is claimed that the present invention can be implemented in the following forms. . As described above, in the embodiment, the negative electrode surface of the diode D disposed in the rectifying power is connected to the secondary coil % of the tBJ electric wisher. However, as shown in FIG. 7, the negative electrode of the diode D which is placed in the rectifier circuit can be switched to the capacitor. When the voltage is generated, the voltage generating circuit 2 supplies a positive output voltage V between the discharge electrode 3 and the ground electrode 4. The high voltage generating circuit 2 shown in FIG. 7 supplies a negative output voltage v〇 between the discharge electrode 3 and the ground electrode 4. . . In the above embodiment, the resistance value of the variable resistor Rbf coupled to the positive output terminal of the comparator 系 is changed to adjust the oscillation frequency of the pulse signal ps. Also, the attenuation characteristic of the voltage change 5 of the P 咼 voltage is changed. On the contrary, for example, the first resistor R1 can be replaced by a variable resistor, or the capacitor can be replaced by a variable capacitor. The resistance value of the variable resistor or the capacitance value of the variable capacitor can be changed to adjust the oscillation frequency of the pulse signal Ps. Further, at least one of the resistor, the variable resistor Rb, and the variable capacitor may be changed as required to adjust the oscillation frequency of the pulse signal PS. In the above embodiment, the high power MOS field effect transistor 6 is used as a switching element. However, a bipolar transistor (bip〇lartransist〇r) can also be used instead of the high-power MOS field-effect transistor 6 as a switching element. In the above embodiment, the half-wave rectifying circuit is used to rectify the second voltage generated by the secondary coil 5b. However, the rectifier circuit can also be a full-wave rectifier circuit. In the above embodiment, the oscillating circuit 8 is operated by the comparator 丨丨. In addition to this

X In the above embodiment, a DC power supply E that supplies a U volt is used. However, for example, a DC power supply with a full-wave rectification circuit for rectifying the mains input into the 201116336 can also be used. In the above embodiment, the electrostatically atomizing device generates charged fine water droplets by performing electrostatic atomization on water. However, the electrostatically atomizing device can also atomize other liquids other than water, such as moisturizers or chemicals, to produce charged fine droplets having a nanometer size.
